sanity test_161d: FAIL: cat failed

Bug Minor Open Unresolved WC Triage Maloo Wed, 17 Nov 2021 13:58:58 +0000 Sat, 22 Jan 2022 17:30:29 +0000 0 3 <p>It looks like this has been failing for a long time, so it isn't easy to attribute it to a specific patch, and it may be that the subtest has been failing since it was first added. Given the large number of different failure modes for this test, I suspect it is just a flakey test that depends too much on timing to work reliably.</p> <p>I searched back in the test results. It has failed 15 times in the past 4 weeks, and going back further to 2020-01-01 I found 74 failures with this message in 2020, and 45 in 2021, but the distribution is quite uneven (e.g. there were no failures between 2021-05-30 and 2021-08-01, even though this subtest was run thousands of times between those dates).</p> <p>It would be useful to improve the "<tt>cat failed</tt>" message to remove the redirection to <tt>/dev/null</tt> to see if the FID could be extracted from the Changelog properly, and what error message "<tt>cat</tt>" is returning. </p> <p>+1 <a href="https://testing.whamcloud.com/test_sets/ee198b48-5a07-46c7-9546-3c4848269c02" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sets/ee198b48-5a07-46c7-9546-3c4848269c02</a></p> Development Rank 1|i02a5r: Rank (Obsolete) 9223372036854775807 Severity
